Linus Torvalds announced yesterday, April 29th, that the fifth Release Candidate of the upcoming Linux 3.4 kernel is available for download and testing.
Linux kernel 3.4 RC5 includes 50% driver updates, 20% Arch. fixes, 15% filesystem improvements (Btrfs and NFS), 5% networking updates, as well as random bugfixes.
"And like -rc4, quite a bit of the changes came in on Friday (with some more coming in yesterday). And we haven't been calming down, quite the reverse. -rc5 has almost 50% more commits than -rc4 had. Not good."
"That said, I don't think there is anything hugely scary there." - said Linus Torvalds in the email announcement.
Download Linux Kernel 3.4 RC5 right now from Softpedia. Remember that this is a development release and it should NOT be installed on production machines. It is intended to be used for testing purposes only.
